Zahran Aloush, the Saudi stooge, has bombarded Damascus with rockets purely for no purpose other than hitting civilians. So yes, he is a terrorist. But can you show us one single proof that Nimr al-Nimr is a terrorist? Has he killed a civilian? Has he blew up himself in a market? Has he touched a gun? Unlike Zahran Aloush the stooge, this guy is in jail only for opposing oppressive Saudi regime. If that makes him a terrorist (obviously because he is a Shia), then indeed, everyone fighting against Assad is a terrorist. That's the logic here.
That's the sole reason that Syrian 'revolution' hit a big wall, because a huge chunk of its followers were nothing but sectarian nutjobs from beginning (with true democracy followers walking somewhere in between), as we can see from different groups and their slogans on the ground. You know your revolution is screwed when you have more than 200 groups in Syria who can't come under one name and flag.
